A: Commonly, police stations or private certified fingerprinting agencies offer fingerprinting service. The fingerprints must be taken in black ink, signed by the official taking your fingerprints and stamped by its agency. In certain countries, these agencies may not offer the signature and stamp. In these cases, alternatively, you can visit Notary Public offices and law firms to have the staff issue you a notarization letter certifying the validity of the fingerprints.
